Immaculate Condition This is a beast of an amplifier which will driver almost any speakers with ease. Enables you to drive your 3 front channels if you wanted to taking the performance level of your surround system to an entire new level. Each of the 3 channels can be switched independently to use either RCA or XLR (fully balanced).   Unlock the sound of your AVR with a top performer (I rate Parasound above and beyond Rotel and Arcam).  It is superb in stereo use only and has been paired beautifully with different B&W which are reputed to be hard to drive.   It uses full class A for the first watts before switching to AB class operation which means that at even low volume the sound is engaging and dynamic. The reserve of power will give you the headroom for amazing dynamic. Grab yourself a fantastic piece of equipment (happy to demonstrate).
